INDIANAPOLIS -- If you wanted a spicy start to Super Bowl XLVI, you got it, as the Giants drew first blood when a Tom Brady throw from his own end zone drew a flag, a penalty for intentional grounding and a 2-0.

For those of you scoring at home, betting on a safety as the first score in the Super Bowl was a 75:1 bet at Sportsbook.com. In other words, it's not likely to happen, but it did. (And they're saying someone won $15,000 on a $200 bet.) The only time a safety was the first score in an NFL championship, with a safety happening in Super Bowl IX as well.

The stranger occurrence was the Patriots defense managing to wake up and get pressure on Eli Manning after the Giants quarterback looked poised to carve them up in the early going. Manning went 4/4 for 40 yards on the first drive and pushed the Giants into Pats territory.

The odds won't be tilted quite as heavily towards the Patriots this time, though, as New England's been installed as "only" a three-point favorite according to Sportsbook.com. R.J. Bell of PreGame.com notes that the Patriots are a 3.5-point favorite.

When the two teams met in 2007, the Patriots closed as 12-point favorites in Vegas, but, of course, ultimately ended up losing straight-up.

Bell notes that the Vegas favorite has won 33 of 45 Super Bowls in NFL history, or 73 percent of the games played.

"Historically, the point-spread is an unmatched predictor of NFL games," Bell notes.

Currently, the over/under for the Super Bowl is a whopping 55.5 points according to Sportsbook, which means Vegas expects to see plenty of scoring from the two teams. That's no surprise given the Eli Manning-Tom Brady matchup and the pair of explosive offenses featured by the two teams.

Speaking of big numbers, Bell projects that over $10 billion -- yes, with a "b" -- will be wagered on this year's Super Bowl.
